2 Claims.

My invention relates to a gas burner.

The principal object of my invention is to provide a burner havingremovable parts for the convenience of cleaning the same, and moreparticularly the jets.

A further object of my invention is to provide a gas burner withremovable members that form the sides of the jets, the said membersremovable and replaceable without the use of tools.

A still further object of my invention is to provide a mixing chamberfor the fuel in direct communication with the jets, and a baille plateas distributing means for the fuel to the jets, and also an inletadmitting air to the chamber simultaneously with the gas injection, andmeans to control the air supply.

A still further object of my invention is to provide a series of jetsformed to avoid contraction of the flame ascending therefrom to a point,and furthermore the ignition and burning operations are practicallynoiseless.

These and other objects will be hereinafter more fully explained,reference being had to the accompanying drawing forming a part of thisspecification in which like characters will apply to like parts in thedifferent views.

Referring to the drawing:

Fig. 1 is a plan View of the burner, parts removed for convenience ofillustration.

Fig. 2 is a side view of Fig. 1, partly in section.

Fig. 3 is an enlarged side view of one of the bars, forming the jets,and showing the spacing lugs.

Fig. 4 is a top view of a plurality of the bars showing their relativepositions.

Fig. 5 is a sectional view of the mixing chamber taken on line 55 inFig. 1, looking in the direction of the arrow.

Fig. 6 is a plan view of the burner modified to make it adaptable tokitchen ranges, or thelike.

The invention herein disclosed consists of a mixing chamber, I,substantially rectangular in form for the main portion of the body, buthaving one side wall funneled, extending outward as at A, to which isconnected an air inlet having a mouth, 2, with an air controlling plate,3, axial- 1y aligned in front of the mouth and removable to and from thesame, by which means the air enters the gas chamber simultaneously withthe gas as supplied by pipe, 4, the flow thereof being controlled by avalve, 5, substantially as shown.

Along the upper inside edge of each of the oppositely disposed sidewalls, B and C, is a shoulder, D, spaced downward which form bearingsfor the ends of a plurality of bars, 6, closely engaging to cover theentire area of the open portion ofthe chamber, and each bar hasintegrally formed spacing lugs on one side thereof as at E and F, bywhich means, when the said bars are snugly assembled as shown in Fig. 4,a series of slots, 1, are formed functioning as jets, through which thefuel ejects for ignition, the method of which is later described.

The upper edge of each bar is arcuate in form inward, or concaveextending from lugs E to F, respectively, as shown in Figs. 3 and 5., bywhich means the vertical extension of the flame from each jet is variedlongitudinal of the same to avoid convergence thereof, it beingunderstood that two series of the jets are arranged, one being on eachside of the said lugs, F.

Extending across the mixing chamber is a baffie plate, 8, obliquelydiverging from the center each way as shown in Fig. 1, the said platebeing joined to the bottom and side wallsof the chamber, respectively,the upper edge of which plate is spaced downward from the lower edge ofthe said bars, 6, by which means the fuel is distributed and furthermixed by diversion thereof by the plate to each side and thence oversaid plate into the rear portion of said chamber body.

It is advisable that a pilot light be employed for large burnersfunctioning in heating plants, in which case I have arranged a pipe, 9,having an orifice jet, ID, on the discharge end thereof, positioned inclose proximity to. the flow line of fuel through the jets, the otherend of said pipe being connected to the supply pipe, 4, outward from thevalve, 5, for continuous burning, by which means, where the said gasburner is thermostatically controlled, the fuel supply at all times willbe ignited by the pilot.

It is now clearly shown that the mixing chamber of said gas burner thusarranged is easily cleaned by removing the bars as accessible means tothe interior thereof, and each bar is easily cleaned from sedimentaccumulation, after which said bars are replaced in their order, namely,the smooth side of each bar abutting the lug side of its adjacent bar assaid bars are placed in the opening of the mixing chamber, the noiselessfeature of said burner being due to the elongation and position of thejets and by a liberal sized mixing chamber co-acting therewith.

While I have shown rectangular and circular mixing chambers and aninward arc for one edge of the jet bars, I do not wish to be confined tosuch form alone, as the same may be modified to end of the bar, wherebya depression is formed between said lugs, the said lugs adapted to spacethe straight side of a similar bar from the depressions to form a jetfor the flow of gas from the said chamber, and the said end lugs beingmeans to close the space between the bars from the outer extremity ofeach end a short distance inward, the upper surface of each bar beingarced inwardly between the lugs, all substantially as shown.

2. As an element of a gas burner, an elongated 10 bar carrying aplurality of spacing lugs, and having a longitudinally concave uppersurface.
